Witchers Trio. Vesemir, Eskel, Lambert. Why so bad?

Recently I’ve been thinking about these combo a lot, I mean, those cards are not bad, they are terrible.
Playing 9 points for 21p and 600 scraps with big chance of bricking.
Even Roach and Knickers are better cards, cause you just have to have them in the deck and they’ll do their job.
But with those you have to have only in hand, wait for adrenaline 4 and then get boom, 9 points.
Damn, even stupid Affan is better (still have no idea why this card is 800 scraps)

I think, for these combo to be really viable and see some play they should just jump out on their own with some condition, like whenever you play gold Witcher card or any Witcher something like this.

Does anyone uses them as a playable cards or everyone use them just for the sake of cool artwork they make together?

P.S. it’s not a rant, just exploring the cards and finding so many terrible cards it’s shocking. I had another thread with 8-10 bad cards
